Mine doesn't return to cold-n-dark after changing the fuel. It can revert to cold-n-dark after going into the menu, but I can't remember exactly where in the menu I go to where it has done that. So no fix that I know of for that. Sorry. I often wonder if it might be the way some people use FSX. Here's how I use FSX: - I always run FSX in windowed mode, never full screen. This allows me to go to other areas of Windows (i.e. a tutorial.pdf), or whatever, and return to FSX without having to press ALT+ENTER twice to be able to see FSX on my screen again. I also get better frame rates in Window mode than I do in Full Screen mode. Of course it comes down to personal preference, and that happens to be mine. ;) - I always run FSX using "Run as administrator", but that's only because I have one addon aircraft that doesn't work unless I use FSX with it. So I has a valid reason for doing that.

Mark,

I was doing a nightflight earlier on. I paused the sim and returned to it now and moved the time forwards.The plane reverted to  cold-n-dark and it was basically game over. Too bad.

I get better frame rates full screen.The apps that I run when I use the sim are installed on a networked  pc.
